15. In addition to the foregoing data, the claimant should state the names of 
adjoining claims, or, if none adjoin, the relative positions of the nearest claims; 
should drive a post or erect a monument of stones at each corner of his surface- 
ground, and at the point of discovery or discovery shaft should fix a post, stake, 
or board, upon which should be designated the name of the lode, the name or 
names of the locators, the number of feet claimed, and in which direction from 
the point of discovery; it being essential that the location notice filed for record, 
in addition to the foregoing description should state whether the entire claim 
of fifteen hundred feet is taken on one side of the point of discovery, or whether 
it is partly upon one and partly upon the other side thereof, and in the latter 
case, how many feet are claimed upon each side of such discovery-point. 
16. Within a reasonable time, say twenty days after the location shall have 
been marked on the ground, or such time as is allowed by the local laws, notice 
thereof, accurately describing the claim in manner aforesaid, should be filed for 
record with the proper recorder of the district, who will thereupon issue the 
usual certificate of location. 
17. In order to hold the possessory right to a location made since May 10, 
1872, not less than one hundred dollars’ worth of labor must be performed, or 
improvements made thereon annually until entry shall have been made. Under 
the provisions of the act of Congress approved January 22, 1880, the first 
annual expenditure becomes due and must be performed during the calendar 
year succeeding that in which the location was made. Expenditure made or 
labor performed prior to the first day of January succeeding the date of loca¬ 
tion will not be considered as a, part of, or applied upon the first annual expend¬ 
iture required by law. Failure to make the expenditure or perform the labor 
required will subject the claim to relocation by any other party having the 
necessary qualifications, unless the original locator, his heirs, assigns, or legal 
representatives have resumed work thereon after such failure and before such 
relocation. 
18. The expenditures required upon mining-claims may be made from the 
surface or in running a tunnel for the development of such claims, the act of 
February 1 1, 1875, providing that where a person or company has, or may, run 
a tunnel for the purpose of developing a lode or lodes owned by said person or 
company, the money so expended in said tunnel shall be taken and considered 
as expended on said lode or lodes, and such person or company shall not be 
required to perform work on the surface of said lode or lodes in order to hold 
the same. 
19. The importance of attending to these details in the matter of location, 
labor, and expenditure will be the more readily perceived when it is understood 
that a failure to give the subject proper attention may invalidate the claim.
